The last time I specifically mentioned coparenting to her was a good while back (about 2 years ago) when she was still responding with hatefulness and refusals to coparent.
The other day when my brother talked to her about our kids and their difficulties, she told him that she still harbors resentment toward me. And she mentioned to my brother that maybe he could "mediate" for us.
He told me last night that "you said you wished exW happiness; the defining moment, I believe will be how you convey this to her. I feel that when this is done YOU will be able to Completely put THIS chapter behind you."
He thinks things will be better between she and I when she knows that I will not pursue anymore and she'll feel more comfortable communicating with me about our kids. He also thinks it'll help for her to know that my only concern anymore with communicating with her is about our kids.
